ANN ARBOR -- Everyone knows who Denard Robinson is.

But no one has a clue where he'll be selected in the NFL draft.

The former Michigan quarterback continued to slide from the third to the sixth round in mock drafts, even on the eve of Thursday's first round (8 p.m., ESPN and NFL Network). And no one really knows where he'll player, either.

Robinson had a indelible career at Michigan, racing into the record books as the all-time FBS quarterback rushing leader. He set the school record for touchdowns with 91.

But what's the best way to exploit those abilities in the NFL?

That likely will remain a mystery until he finds a home. And when he'll find a home remains just as much a mystery.

Robinson won't be selected in the first round, but holds out hope he can go sometime during the second and third rounds Friday. The latest projections suggest Saturday's fourth through sixth rounds are more realistic.

He's the headliner of Michigan's meager draft class. Here's a closer look at him and his fellow hopefuls:

Awards: All-Big Ten honorable mention (media only) in 2012, second team (media)/honorable mention (coaches) in 2011 and first team (media)/honorable mention (coaches) in 2010. Big Ten offensive player of the year in 2010. FWAA All-American at running back in 2010. Michigan team MVP in 2011 and 2010. Sixth in Heisman voting in 2010.

Stats: Passed Pat White in his final game to become the FBS career quarterback rushing leader (4,495 yards) and is second overall at Michigan. Also holds the NCAA season record for rushing yards by a quarterback (1,702 yards in 2010). Is the first player in NCAA history to pass for 2,500 yards and rush for 1,500 yards in a single season (2010). Fourth player in history to twice gain 2,000 yards passing and 1,000 rushing in a season, joining Missouri's Brad Smith, UAB's Joe Webb and Nevada's Colin Kaepernick. Eighth player in NCAA history to rush for 40 touchdowns and pass for 40 touchdowns. Set school record for total offense (10,769) and touchdowns (91). Had 20 100-yard games, second in school history.

Did you know? Robinson owns the top eight single-game offensive outputs in Michigan history, and ten of the top 11.

What they're saying: “I am a weapon. When I get on the football field, I feel like I am a weapon. When I get at that running back position, I can take it the distance. I can take the pounding of getting hit a couple times. I can go at receiver and make cornerbacks look bad. I think I can bring that to the table. Once I get the ball in my hands and I’m in open space, I can’t be tackled one on one. That’s my motto: 'Every time I get the ball, it’s time for me to get in the end zone.'” -- Denard Robinson on ESPN Radio 98.7 in New York

"He’s going along in the right direction as far as developing his skills to be a returner. He’s also got some ability to play running back. We went back and watched him play running back those last few games. He’s sort of got those slash qualities as a receiver, possibly a slot receiver and a half back." -- Detroit Lions general manager Martin Mayhew

"I still don’t know where he’s going to play. I’ve asked teams. I’ve tried to watch him and figure it out -- if he’s a receiving entity, if he’s a running entity, if he’s a defensive entity at corner, a return guy. I’ve been trying to find the best position where he could carve a niche. It’s not defined right now. ... So where does he go? Third, fourth round. I could see somebody taking him late Day 2, early Day 3." -- ESPN's Mel Kiper Jr.

The skinny: Robinson was a record-setting quarterback at Michigan, but is attempting to make the NFL either at receiver, tailback or a combination of the two. He's shown growth at receiver since making the move in January, although questions persist about his hands and instincts at the position. He moved to tailback for the pro day, and has piqued interest there, including from the Lions. His stock continues to fluctuate wildly, even on the eve of the draft, but is expected to be selected sometime in the middle rounds. He might be something of a project, but he's a proven offensive playmaker with the ball in hands. And you can't teach electricity.

Stats: Played in 51 consecutive games, starting 11 times at defensive tackle. Posted a career-high 44 tackles as a senior, after combining for 19 in his first three seasons. Also had three sacks and one fumble recovered.

Did you know? Campbell lived out of a hotel for six weeks during draft preparations. He stayed at the Embassy Suites in downtown Indianapolis while training at St. Vincent Sports Performance. The only thing he brought from home, besides the essentials, was an X-Box. He also watched a lot of "Duck Dynasty" on A&E.

What they're saying: "I'm kind of mad I matured so late. I mean, it's all on me. It was me being lazy, me not listening to the coaches, me not fitting in their scheme, me being too big, not being fast enough. ... I just want for that not to happen again -- for me to have to watch from the sideline, to not have a chance to play. I don't want to be a spectator. I don't want to watch anymore. I just want to play." -- Will Campbell

"I like him on tape. I just think he's strong. He's a guy who can take up space and I think fits well in the 3-4, and there's value there. I just think he has to continue to improve his hands and do some little things to improve as a player, but he can play at the next level." -- ESPN's Todd McShay

The skinny: Campbell loafed through much of his Michigan career, but the specialized coaching of Brady Hoke and Greg Mattison -- defensive line guys by trade -- helped him post a strong senior season. It was enough to get him on some NFL radars, and scouts continue to rave about his physical tools. But he's also drawn criticisms for not being consistent. Campbell could make a club either on defense or offense, the latter of which has surprised him. But teams called his agent with interest in him on that side of the ball, and he says he's willing to do whatever it takes to make a roster. Campbell hasn't produced like a draft pick, but he's a big body in a market that lacks them on the defensive line. It wouldn't be surprising for a team to take a seventh-round chance that they can finally help him pull together his physical gifts.

Awards: Team MVP in 2012. All-Big Ten second team (coaches)/honorable mention (media) in 2012, honorable mention (media) in 2011 and honorable mention (media) in 2010. Sporting News freshman all-Big Ten team in 2009.

Stats: Played in 50 games, making 46 starts at safety. Ranks 12th in school history with 331 tackles. Was second in the Big Ten in tackles (116) in 2010. Finished with 26 career tackles for loss, including seven sacks. He also recorded two fumbles, forced six and picked off five passes.

Did you know? Kovacs, a three-time all-Big Ten player and a team captain as a senior, is nearly $100,000 in debt after spending two years as a walk-on. That out-of-state tuition will really get ya.

What they're saying: "I wasn’t born with a silver spoon, so to say, at the University of Michigan. Far from it, to be honest with ya. I had to walk-on twice. I had to basically convince the coaches to take me, and just had to be stubborn about it. It’ll be interesting to see how the guys that never really had to work to be on a roster, how it plays along for them, because I’m confident in what I had to do to make it at Michigan, and I’m confident I can do it again in the NFL." -- Jordan Kovacs

"Kovacs is another guy who's going to make a team. A Jim Leonhard-type player who throws his body around. Played in a lot of games, but you wonder if he'll be able to hold up physically with his style of play at only 5-11, 205." -- ESPN's Mel Kiper Jr.

The skinny: Kovacs continues to face size and speed questions, as he did when he was coming out of high school without a single FBS offer. He built an incredible career for himself at Michigan, despite those challenges, and believes he'll prevail in the NFL as well if given a chance. The problem is, can Kovacs compete with elite athletes in the NFL? He's a brilliant player, and although that goes only so far, it could land him in a camp and help him compete on special teams. He could be drafted, although it's more likely he is signed as a free agent.
